Power converter for ion thrustors with pulse width modulated bridge inverter with silicon power transistor using current feedback base drive
Design verification tests for logic and low level circuits, and preliminary single-phase breadboard of pulse width modulated static inverter
Centaur solid state inverter failure during simulated flight in environmental space chamber
In the production of high temperature by electron bombardment the cathode is held at ground potential while the hot anode is raised to a high negative potential. An annealing chamber using the inverted grounding is constructed around a commerically available stainless steel cross.
Breadboard models and interface requirements for optimum performance and reliability of inverter motor system
